Windows Explorer will open to your Logos 4 folder. In the Address bar, click the "Local" folder as pictured below (XP Users will have a "Higher Directory" button).

In the Local folder (XP=Local Settings), Right-click the Logos4 folder and from the Carbonite menu, select "do not backup this item".

Close all open windows, Carbonite will simply skip to the next folder it needs to backup and Logos 4 should update and run correctly now.

This problem may apply to other "backup" programs. Because Logos 4 creates a backup for you automatically (active internet connection required), there is no need to use a 3rd-Party backup program for your Logos 4 files. You should be able to follow similar steps to disable backup of the Logos4 folder in other backup programs, but the exact steps may vary.
